the most common thing will be "Zugbeeinflussung" which translates to "train influencing". This comes up everytime you manipulate the PZB system, like freeing yourself from the 40km/h limitation and what not. When booting up the ICE the voice says "Türen geöffnet" (doors open), "Störung" which is "fault" or "disorder" and Zugbeeinflussung. There is one other thing that is said twice but even I can't fully understand it, only something with "gesperrt", meaning "locked" or "disabled" depending on the context. Also a female voice will repeat "AFB" when you are turning on the AFB control. AFB is short for "automatische Fahr- und Bremssteuerung" and should translate to "automatic acceleration and break control" and assists the driver in keeping the train at the preset speed. Then you have Sam's infamous "SIFA", which is a short for "Sicherheitsfahrschaltung" and translates to dead man's vigilance device. If you miss pressing the SIFA a voice will tell you "Sifa Zwangsbremsung", which is emergency break and sifa being the reason. If you fail the PZB check a voice will tell you just "Zwangsbremsung", e.g. emergency break. And when closing the doors it says "schließvorgang eingeleitet", which just means the doors are closing. Hope that helps!
